Scalper screen: Various applications and usage | Etrack Crushers

Stone crushers are mainly used to break large stones into smaller sizes. But, nowadays, mobile stone crushers are also used in many other fields. For example, some industries use them as gravel screens.
When it comes to mobile stone crusher, scalper screens are one of the most important parts of the machine. They play a variety of roles in the crushing process, and there are a number of different applications and usages for them. In this blog post, we’ll take a look at some of the different ways that scalper screens can be used in mobile stone crushers.

What is a scalping screen?

A scalper screen is a construction industry term for a metal-framed layer with gaps to act as a filter for the segmentation of the material coming out of a mobile stone crusher. The name “scalper” comes from the fact that these partitions can be quickly and easily assembled, like a stack of cards (or “scalps”). Scalper screens are typically used on construction sites as silt to section off gravel size and control the flow of particles.

A scalper screen of mobile stone crushers is a screening machine that separates large boulders from smaller rocks. It has a series of screens or meshes that the stones pass through. The size of the rocks dictates which mesh they will fall through. This type of screening machine is most often used in quarrying and mining operations to separate different sizes of stones for further downstream processing.

A scalper screen in stone crushers is a kind of vibrating screen. It uses the vibration motor as the power. It drives the eccentric shaft to make the screen body make the linear reciprocating motion. The materials are fed into two ends of the screen box and then go through the screening process simultaneously.

The advantages of scalping screens

One common application for scalper screens is separating large stones from smaller ones. This helps to ensure that only the desired-sized stones are passed on to subsequent stages in the crushing process, which can improve efficiency and reduce wear and tear on other parts of the machine. Scalper screens can also be used to remove fines from crushed material before it’s discharged from the crusher. This helps to improve overall product quality by removing smaller particles that can cause problems downstream.

Another key role played by scalper screens is controlling particle size distribution. By adjusting the screen settings of the gravel screen, operators can control how much material passes through each screen opening, allowing them to create gradations according to their needs. This is an important part of ensuring that products meet specific requirements for size and shape before they’re sent off for further processing or sale.

The benefits of using a scalper screen are manifold: 

• By separating large boulders from smaller rocks, you can save wear and tear on downstream machinery by not having to process larger pieces than necessary; 
• The use of screens allows for more accurate sizing and separation of materials, resulting in less waste; 
• Screens can be set up so as to remove oversize material before it enters the crushing chamber, reducing wear on crusher parts; 
• A well-maintained scalper screen can increase production by allowing for more efficient separation and handling of raw materials.

How to select a scalping screen for your business? 

The scalper screens have been widely used in many industries such as quarrying, coal preparation, ore dressing, building materials, chemical industry, and so on. They are mainly used for screening and grading large-sized materials or removing impurities from small-sized materials. 

There are many types of scalper screens with different sizes and screening areas. According to various applications, they can be divided into three categories: coarse type scalper screens (usually used for big-sized materials), medium type scalper screens (traditionally used for middle-sized materials) and fine type scalpers (usually used for materials).

The first step is to determine the desired output size of the crushed stone. Once this is known, then a scalper screen with the appropriate aperture size can be selected. A mesh with coarser openings will be needed for smaller outputs, while a screen with finer slots will work best for larger outcomes.

Another important consideration when selecting a scalper screen is its shape and curvature. Suppose there are many large rocks in the material to be crushed. In that case, it may be necessary to use a curved or concave-shaped scalper screen that can help deflect these larger rocks away from the crusher itself. Otherwise, they could potentially damage it or reduce its overall performance.

There are many factors to consider when selecting a scalper screen for a stone crusher. The most important factor is the size of the stones that will be passing through the net. The opening size of the scalper screen must be large enough to allow all of the rocks to pass through but small enough so that no fines or dust escape from between the stones.

The second consideration is how much wear and tear the scalper screen can withstand. Stones can be very abrasive; over time, a scalper screen with too little durability will quickly become worn down and need replacement.

Finally, it is important to find a scalable solution that can grow with your business as production needs increase. A scaler screen should be able to handle larger quantities of material as your business grows without requiring significant modifications or upgrades.

Conclusion

There are many different ways that scalper screens can be used in mobile stone crushers to help optimize performance and achieve better results with less wastefulness. Using a scalper screen will help to keep the crusher running smoothly while also reducing the amount of material that is wasted.

In addition to improving performance, scalper screens can also help to improve safety. Suppose there are any large or dangerous stones present in the material being processed by the crusher. In that case, using a scalper screen will remove them before they enter the crushing chamber. This can help reduce wear on both the machine itself and on any workers who may be nearby. Overall, there are many benefits to using a scalper screen in conjunction with a mobile stone crusher. Not only can it improve performance and safety, but it can also save you time and money by reducing wastefulness.
